Locality type:
Köppen climate type:
Structure: Mobile Belt Deposit Is Along West Side Of Nightingale Block-Faulted Range; Caldera Margin
Alteration: Argillization Of Rhyolite With Hematite; Silicification Of Rhyolite Away From Fault
Tectonics: Central Part Of Eugeosynclinal Part Of Nevada Basin And Range.
Deposit: Yellow uranium minerals in breccia fragments, but breccia zone is not fully mineralized. Zone may be better at depth. Uranium mineralization is fault-controlled. Current ore exposed is just below old lake lahontan level, which may have produced some concentration just below water level. This record has been merged with record m242695, which has been deleted.
Development: Area prospected in early 1950s, by dozer trenching, one adit 200 feet long. Recent (1978) dozer work and shallow 4-foot hole (adit) indicate continued interest in the prospect.
Geology: Ash flow and ash fall tuffs are preserved in down-faulted areas which have had further volcanism; andesite partially buries rhyolite to the northwest. Area has appearance of caldera minus central uplift. Fine, crystalline, red, silicified rhyolite, argillized and broken by faulting. Unaltered rhyolite shows some green ferrous oxide coloration. A wedge of auld lang syne sediments abuts against the fault on the south and is surrounded by intrusive rhyolite. Deposit is associated with an intrusive rhyolite dike in or near the edge of the caldera. Uranium occurs in form of secondary minerals in NW trending sheeted zones in rhyolite ash flow tuff of hartford hill rholite and tuffaceous sandstone and conglomerate of the chloropagus formation.
Rock formation(s): Auld Lang Syne;Hartford Hill Rhyolite;Chloropagus Formation
Ore(s): N 70 W Fault In Volcanics; Uranium Probably Leached From Rhyolite Tuffs, Redeposited In Fracture Zones
